Nominal

adj. relating to or being a name; relating to or being a noun (Grammar); very small; token; in name only, so-called

The adjective nominal (ultimately from Latin nōmen, "name") generally relates to the concept of names, and often to the difference between what something is in name (ideally or theoretically) and what it is in reality.A nominal quantity (e.g., length, diameter, speed, volume, voltage, value) is generally the quantity according to which some item has been named or is generally referred to. Such a nominal value may often be different from the actual value, having a relation to the actual value that is anywhere on a spectrum from closely related (for example, differing only within a range of acceptable random variation]) to only distantly related. An example of the former is a type of battery that has an actual voltage of 1.62 V, but is called a "1.5 volt battery"; it has a nominal voltage of 1.5 V (which cannot be measured anywhere). An example of the latter is the nominal size 2×4 for dimensional lumber: its actual size is 1½″ × 3½″ (38×89 mm) (plus or minus some small tolerance).
